My nephew has an original 283 in his 64 mooredoor... the car performed OK but we decided to swap a TH350 behind it so we bought a good used one and the converter and put a shift kit in it.

1. Now the question is we have the original 153 tooth flex plate but doesn't have the raised mounting hole areas for the converter like all of the new ones seem to have. Is this going to affect the 350 converter spacing?

2. I also showed up and he had the converter on the flex plate ready to put the tranny on. Is here any drawback to doing it that way or should it go into the tranny first then mate it to the engine? He said that the lugs were straight vertical and all lined up.

question #2 it is critical to install the converter into the front pump of the
transmission you need install this correctly spin converter slowly so it
seats down into the pump!! flex plate should be attached the cranshaft
then trans can be bolted up
